Given numbers are 605,740,631,288,518
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,740,631,288,518 is 28475868960.
Find LCM of 605,740,631,288,518 with Prime Factorization
| 2 | 605, 740, 631, 288, 518 |
| 2 | 605, 370, 631, 144, 259 |
| 5 | 605, 185, 631, 72, 259 |
| 37 | 121, 37, 631, 72, 259 |
| 121, 1, 631, 72, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 37 x 121 x 1 x 631 x 72 x 7 = 28475868960
Therefore, the lowest common multiple of 605,740,631,288,518 is 28475868960.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
605 x 740 x 631 x 288 x 518 = 42144286060800
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
605 : 1, 5, 11, 55, 121, 605
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
631 : 1, 631
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
518 : 1, 2, 7, 14, 37, 74, 259, 518
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,740,631,288,518, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
740:2x 2x 5x 37
631:631
288:2x 2x 2x 2x 2x 3x 3
518:2x 7x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 5x 37 = 1480
Therefore, the value for common factors is 1480.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 42144286060800/(1x1480)
LCM = 42144286060800/1480
LCM = 28475868960
Thus, we can understand that the LCM of 605,740,631,288,518 is 28475868960.
